THRESHER.

SPECIFICATION forming part Of Letters Patent N0. 715,066, dated December 2, 1902.

Applioationfiled November 20, 1901. Serial No. 83,043. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM A. HESSE, a citizen of the United States, residing at Redbluif, in the county of Tehama and State of California, have invented new and useful Improvements in Threshers, of which the following is a specification.

This invention relates to harvesters and threshers, being designed with special refer-- ence to combined harvesting and threshing machines by which the grain is gathered and threshed by the same machine as it is drawn along the field.

The primary object of the present invention is to produce an attachment consisting of a supplemental or extra sieve which is placed in the bottom of the cleaner and associated with hanging and adjusting devices in such manner that said supplemental or auxiliary screen may be adjusted as to its angles so as to cause it to operate properly when the machine is going uphill, preventing the grain from falling over the end of the screen into the spiral conveyer and causing said grain to be delivered from the cleaner into the usual sacks or receptacles provided therefor. By this means not only is a saving of the grain effected, but it is delivered in a clean condition and in a constant rather than in a broken or intermittent stream.

With the above general objects in view the invention consists in the novel construction, combination, and arrangement of parts hereinafter fully described, illustrated, and claimed.

The accompanying drawing represents a vertical longitudinal section through the cleaner of a combined harvester and thresher, illustrating the application of the present improvement.

Referring to the drawing, 1 designates the body or frame of the cleaner, the bottom edge 2 of which has a configuration which adapts it to fit snugly upon the main body of the combined thresher and harvester, the said frame of the cleaner comprising a transversely-extending trough 3, in which is arranged a spiral conveyer l, underlying one end of the usual stationary screen 5.

Above the stationary frame 1 is arranged the pivotally-mounted portion of the cleanerframe, said pivoted portion being indicated at 6 and shown as connected by transverselyopposite pivots 7 with inverted V-shaped standards 8 extending upward from the stationary portion of the cleaner. The pivoted portion of the cleaner comprises a fan-casing 9, in which is arranged a rotary fan or blower 10, adapted to direct a strong current of air toward and through an initial set of screens 11, 12, and 13, said screens being permanently connected With the movable member 6 and arranged at an inclination one above the other with their receiving ends disposed beneath the discharge-orifice 14 of a superimposed hopper 15, to which the grain is delivered by means of the usual grain-elevator. (Not shown.)

The pivoted member 6 of the cleaner-frame is provided along its upper side with a handlever 16, by means of which the memberd may be tilted. The rear end of said lever is arranged in convenient position to be grasped and operated by the attendant, while the opposite or forward end of said lever is provided with a spring-catch 17, the free end of which is provided with a pin or projection 18, adapted to be engaged in any one of a series of openings 19, formed in a lever-standard 20, which is pivotally connected at its lower end, as at 21, to the stationary member 1 of the cleaner frame or casing. By means of the lever 16 and standard 20 the pivoted member of the cleaner-frame may be swung on the pivot 7, so as to vary the inclination of the initial set of cleaning-sieves, as indicated by the full and dotted line positions in the drawing.

Located just above the stationary bottom screen 5 is what I term an auxiliary bottom screen 22, which is hinged at one end, as at 23, to the adjacent end of the stationary bottom screen. The opposite or free end of the screen 22 is connected, by means of one or more hangers 24, with the upper pivoted section 6 of the cleaner, each hanger preferably consisting of a chain or similar connection having at one end a bolt or rod,which is adjustably mounted in an eye Orbraoket 25 on the member 6, said rod being adjustable by means of a binding-screw 26 passing through the bracket 25. The lower end of the hanger rod or bolt is threaded to receive a nut 27, so that an adjustment may be effected either at the upper or lower end of the hanger 24E.

From the foregoing description it will be seen that the bottom screen may be tilted and adjusted as to its angle with relation to a horizontal plane so as to adapt the machine to operate as well in moving up an incline as in moving along a level surface. v In this way the grain is prevented from falling over the edge of the screen into the conveyer-trough and is caused to pass oif the opposite end of the screen, where it is discharged into a sack or other suitable receptacle. Not only is a saving of grain effected in this way, but it is brought out cleaner and in a constant stream.

The improvement described does not interfere in any way with the end shake which is ordinarily given to screens. It will also be understood that the initial set of screens is adjusted simultaneously with the auxiliary bottom screen.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

A cleaner for harvesters and threshers, comprising a stationary member, a stationary bottom screen connected therewith, a pivoted member, an auxiliary bottom screen hingedly connected at one end to the stationary bottom screen, an adjustable hanger connecting the free end of the auxiliary bottom screen with the pivoted member of the cleaner, and means for adjusting the angle of the pivoted member of the cleaner and fixing said adjustment, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM A. HESSE.
